Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic-thermal integration, and particularly relates to a photovoltaic-thermal integration device. Background Technique

[0002] The photovoltaic-thermal integration system organically combines photovoltaic power generation and a solar collector. While performing photoelectric conversion, the heat of photovoltaic cells is recovered by using a cooling medium to complete the full-spectrum utilization of sunlight. Sunlight passes through a concentrating element and irradiates on a photovoltaic panel, generating electric energy due to the photoelectric effect. The electric energy is incorporated into the power grid through an inverter, and the remaining energy of sunlight is transported outward in the form of heat energy. The working medium flows through the PV / T module under the action of a circulation pump, absorbs the heat of the photovoltaic panel, reduces the temperature of the photovoltaic panel, and then enters a hot water storage tank for sufficient heat exchange. The hot water obtained therefrom can meet the needs of residents' lives and industrial production. The PV / T module can also be used as a heat source for a heat pump or a heat pipe to complete the reuse of low-grade energy, having strong economy and flexibility. There are certain drawbacks in the use of existing photovoltaic-thermal integration devices. Since the heat absorption plate and the heat absorption pipeline are located behind the solar panel, the temperature of the heat collection plate is limited by the temperature of the solar panel, which in turn leads to a low temperature of the heat exchange working medium inside the pipeline and low utilization rate. When adjusting the angle of the solar PV / T module, it is easy to be misaligned and stuck due to different rising or falling heights on both sides, making it difficult to adjust accurately. Therefore, we propose a photovoltaic-thermal integration device. Content of the Utility Model
